先上json的数据格式,底部有完整的php
{
"id":0,
"success": true,
"user":{
"ready":"0",
"name":"", //这里声明了name,没有声明tel
"sex":"",
"addr":[{"prov":"1省","city":["a","b","c"]},
{"prov":"2省","city":["aa","bb","cc"]},
{"prov":"3省","city":["aaa","bbb","ccc"]}],
"birth":"1992-06-15",
"wx":""
}
}
问用set方法创建tel的值?
user=this.model.get('user');
user.tel=123;
this.model.set('user',user)
上面这个方法在实际用法无效 tel的值没有加进来
这里却又值
如果文件中存在一个属性,他是可以传值的;
user=this.model.get('user');
user.name=123;//tel换成name
this.model.set('user',user)
访问的数据文件如下:
true));
parse_str(file_get_contents('php://input'),$put_vars);
$put_vars=json_encode($put_vars);
die($put_vars);
die;
}
else{
echo '{
"id":0,
"success": true,
"user":{
"ready":"0",
"name":"",
"sex":"",
"addr":[{"prov":"1省","city":["a","b","c"]},
{"prov":"2省","city":["aa","bb","cc"]},
{"prov":"3省","city":["aaa","bbb","ccc"]}],
"birth":"1992-06-15",
"wx":""
}
}';
}

主要是由于model模型中不存在tel的值;所以无法被保存;所以要在模型的默认属性中先添加tel(空值也好,反正要声明)
你倒底想问什么??先把错别字改掉,把话讲通顺了。
你前端是修改了值然后传到后台吗?把前端的相关代码贴出来吧
既然POST到php的数据是有tel的,说么Model的数据已经修改了,去检查你php的代码,这和Backbone无关
